Idler - domestic bearings can also have a lifespan of 50000 hours
High sealing and long service life idlers
It has the characteristics of high precision, good sealing, low resistance, and long service life. The production process adopts high-precision high-frequency welded pipes, with small radial runout; Stamped bearing seat, CNC machining of positioning surface; The material of the roller shaft is 45 # steel, with CNC turning and grinding to ensure accuracy; Patented low resistance contact sealing technology with self compensation, dustproof and waterproof; The buffer roller tube body is made of seamless steel pipes with high strength; The buffer ring is made of flame-retardant rubber.
Controllable brake roller
Equipped with independent patented technology, it solves the problem of controllable movement along the downward conveyor belt. The bearing seat with a self cooling structure is precision cast, CNC processed and formed, and the roller shaft is made of 45 # steel, which has undergone quenching and tempering treatment and grinding.
Product Introduction
The long-life and high sealing idler designed and produced by Libo Heavy Industry Technology Co., Ltd. is a product approved by the National Innovation Fund. It is mainly developed for the defects of the current belt conveyor idler, such as low manufacturing accuracy, high rotating Drag coefficient, high operating noise, poor sealing, and generally failing to reach the design life. The roller adopts a fully sealed waterproof and dustproof structure, and the bearing components use high-precision bearing chambers and high-quality bearings dedicated to the roller. It has advantages such as exquisite structure, low noise, maintenance free, long service life (over 50000 hours), and reliable performance, making it a good choice for advanced belt conveyor systems.
Product advantages
1. The roller skin adopts high-precision high-frequency welded pipes, with small radial runout and good balance;
2. The bearings are made of stamped parts, with CNC machining for pressing and positioning surfaces;
3. The bearing adopts KA series roller special bearings;
4. The material of the roller shaft is 45 # steel, with high strength, and precision is ensured through CNC turning and grinding;
5. The roller seal adopts a specially designed low resistance contact seal with automatic compensation, which is dustproof and waterproof, ensuring long-term good lubrication of the bearings;
Waterproof and sealing test of roller
After continuously running the roller at 550r/min for 10 minutes under full water conditions, there was no water inflow measured.
On site use cases
At present, the annual output of high life and high sealing idlers has reached about 600000 sets. The company now has two advanced idlers production lines, realizing large-scale production and has been used in large projects undertaken by the company, such as the long-distance ground main transportation system of Yimei Group Cement Co., Ltd., the curved belt conveyor system of Arun Banner 25 km cement mine of Mengxi Logistics Group, and the 10 km mining belt conveyor of China National Building Materials Lishen Cement Co., Ltd, Limestone conveying system of Mount Taishan Cement production line with a daily output of 5000 tons. This roller is energy-saving, environmentally friendly, safe and reliable, saving a lot of costs for the enterprise, and has received unanimous praise from the owners. According to incomplete statistics, the total amount saved by the enterprise is 6 million yuan.
